Influenza vaccination: cost-effective health care for the older adult?

Influenza is a serious cause of morbidity and mortality, particularly in the older adult, and it represents a significant economic burden for health-care services. We have reviewed the published literature relating to influenza vaccine effectiveness and the cost-effectiveness of influenza vaccination in comparison with other health-care interventions and conclude that influenza vaccination is one of the most cost-effective interventions possible in the older adult population.
